EM-4120-0001 Brocade Silkworm 4100 4Gb 16 Active Ports SAN Network Switch

Brocade Silkworm 4100 EM-4120-0001

Brocade's EM-4120-0001 (Brocade Silkworm 4100) is a 4Gb/s Fibre Channel switch that connects servers and storage in small to large Fibre Channel fabrics in the data center. This model is part of the Brocade-based B-Series Fibre Channel family and runs Brocade Fabric OS (FOS).

The listing states 16 active or licensed ports. On many FC platforms you can activate more ports later with port-upgrade licenses. 4Gb/s Fibre Channel speeds keep database, virtualization and backup traffic flowing without congestion. Dedicated storage networking keeps SAN traffic separate from your LAN for predictable performance and stronger security. It works well for fabric expansion or like-for-like replacement. Fibre Channel SFP optics are speed-specific, so choose transceivers that match your target link speed. Confirm HBA, array and transceiver compatibility before joining it to an existing fabric. Redundant fabrics give every host and array a backup path to storage. Dedicated SAN switching protects storage performance from spikes in general network traffic.

Paired switches let you service one fabric while storage access continues on the other. A well-designed SAN fabric makes it easier to migrate data, add arrays and scale virtualization clusters. Part number EM-4120-0001 identifies this exact hardware configuration for straightforward purchasing and asset tracking. Storage vendors publish interoperability matrices worth checking before rollout. Fibre Channel was designed specifically for storage traffic and delivers consistent, in-order frame delivery. Standard switch models in each fabric make upgrades more predictable. The Brocade Silkworm 4100 is a smart investment for anyone who needs Fibre Channel SAN switching.
